WEATHER Application filed 1Toveinber My invention relates-to new, anduseful im provements in weather strippin'gand more character which canbe economically and.

readily applied, and when in applied position will prevent the admissionof dust, cold air, rain or snow around the window or door; r A furtherobject of my invention is the provision of weather stripping which 1sformed with a novel and eflicient attaching flange, whereby when. thesecuring means is applied thereto it will have a tendency to force thebody ofthe strip into close fitting contact with the door or window andat the :5 same time prevent the flange from becoming displaced, or thetearing'or distortion of the flange by the securing means.

To this end, my invention consists in the novel construction,arrangement and combination of parts, herein shown and described, andmore particularly pointed out in the claims.

S'LRIPIEINGL 8, 1926. Serial No. 147,008.

Fig. 9 is an enlarged transverse section with the reenforcement for theflange omitted.

In carrying out my invention, I prefer to provide a filler body ofyieldable packing material such as a rope of cotton, hemp, jute or othermaterial suitable for the purpose, said body being enclosed with aflexible cover sheet having its edges extending beyond one side of thebody and folded to form a securing flange. 1n the present instance,Figs, 1 to 5 inclusive illustrate the preferred embodiment of myinvention and include in its construction the selection of the type offiller body to be preferred, said body being indicated at l and thecover, which is of flexible material, is generally indicated at 2. Thiscover may be of rubber, rubberized cloth or any other similarmaterialcut in strips of suitable length and width and folded longitudinallyaround the filler body 1 so that the body 1 is preferably positionedwithin the fold and the edges ofthe strip are arranged in parallelrelation, one of the edges preferably extending beyond the other edge sothat when these edges are folded upon themselves as shown in Fig. 5, theextremities of the edges will be brought into close fitting engagementwith the main fold of the body strip as shown'at 3 by having said edgesextending onto and conformin to the contour of the body as is clearly ilustrated in Figs. 7 and 9.

From the foregoing it will be apparent that by arranging the edges ofthe cover strip in parallel relation and then folding themuponthemselves, a substantially four-ply securing flange is formed asindicated at 4. In order to increase the strength of the flan e so as toprevent the same from becoming easi y j torn or mutilated by thesecuring means and also to prevent warping or bulging-of the outer edgeof the flange, a reenforcing element 5 is positioned within the foldedover portion of the edges of the cover strip as shown in Fig. 5. Thisreenforcing may be a small rope of cotton, hemp or the like, or may beof wire, rubber or any other material suitable for the. purpose. Afterthe edges have been folded over and the extremities thereof brought inclose engagement with the main fold of the body strip, they are stitchedtogether as shown at 6, said line of stitching being disposed in closeproximity to the filler body 1 so as to securely enclose the filler bodywith:

in the cover sheet and at the same time impart a certain amount ofrigidity to the flange formed by the plies 4.-

It will be apparent that as the filler body '1 is of comparativelyflexible oryieldable material and the cover of a similar nature, theweather stripping can be placed in close proximity or into tight fittingengagement with the door or window so as not to interfere with theoperation of the same but at the same time prevent the entrance of dust,cold air, rain or snow around the window or door. It will also beapparent that by placing the reenforcing element 5 within the doublefold of the edges of the cover strip, the outer edge of the flangedefined by' the plies 4 will be increased in stiflness'so that when thesecuring elements such as tacks or the like are passed through theflange to secure the same to a door or window frame, the reenforcingelement will cause the outer edge of the flange to lie in closeproximity to the frame and thus prevent the outer edge of the flangefrom drawing away from the frame and at the same time will reenforce theedge of the flange to such an extent that it will prevent the securingmeans from being torn laterally through the edge of the flange. Withcertain types of securing means, the

edges thereof may be lapped over the folded I portion in whichthereenforcingelement is placed so as to bring the edge of the flangeinto close tight-fitting engagement with the frame upon which it isplaced and securely retain the same in its effective position.

It may be found desirable in a reat many instances-to eliminate the reenorcing ele- :ment 5, as shown in Fig. 9, and in this case the securingelements which are used to at tach the flange to the window or doorframe are passed through the flange at a point intermediate the outeredge of the flange and the body, the double folded portion of theparallel edges of the cover strip forming suflicient reenforcement forthe outer edge of the flange to prevent the flange from being torn fromthe securing elements and the securing elements ma be of such nature asto bring the double fo ded portion of theflange into tight fittingengagement with the surface to which it is applied in such manner thatthe outer edge of the flange will not draw away from the surface orpermit it to bulge.

In Fig. ,5 the reenforcing element is illustrated in thetform of arubber core, while in Fig. 6 the reenforcing element 5 is shown in theform of a rubber tube, while in Figs. 7 and 8 the reenforcing element 5is illustrated in the form of wlcking.

In Fig. 81 have illustrated in detail cross section the manner in whichthe flange and a portion of the body' cover is brought into closecontact with a window or door frame, and it will be noted that withsecuring means of this type, which is in the form of large headed'tacks7, the heads of the tacks will span the space between the cover of thebody 'ing element adds to further prevent such tearing or distortion.

As stated above, one of the-edges of the cover sheet extends beyond theother edge so that when these two edges are folded upon themselves, theoutermost or longer edge will lap over the extremity of the shorteredge.

and thus permit these extreme outer edges to be fitted closely withinthe curvature between the main loop portion of the body and the edgesthereof as shown at 3. Thus, after the line of stitching 6 has beenpassedthroughthe four plies of the flange, these extreme edges will bebrought into close fitting engagement with the exterior of the body soas to provide a neat appearance for the article itself.

Having thus described my invention, itis obvious that various immaterialmodifications may be made in the same without departing from the spiritof my invention; hence I do not wish to be understood as limiting myselfto the exact form, construction, arrangement and combination of partsherein shown and described, or uses mentioned.

One of the particular features in the construction of weather strippingalong the above lines is that the rubberized surface of the materialused is always exposed to the weather and that the loose edges of thematerial which are connected to the flange part b the stitching 6 isarranged next to the woo work upon which the strippin is attached sothat it eliminates any possibi 'ty of the elements entering between thesheets forming the covering and coming in contact with the unrubberizedside of the material.

What I claim as new and desire to secure by Letters Patent is:

1. A weather stripping including a. body of yieldable material, a coversheet enclosing the body with its edges arranged parallel and foldedupon themselves to form a flange means for connecting the folded portionof the edges at a point adjacent the body, the extreme longitudinaledges of the folded portions extending ontoand conforming to the contourof the body, and a reenforcmg element within the outer fold of the edgesto increase'the rigidity of the flange.
